Nobody wants to wake up worried about bed bugs or a spilled drink soaking into their mattress. That’s exactly why I set out to find the best waterproof mattress protector that protects against bed bugs — something that blocks liquids and locks out creepy crawlers without feeling like a plastic bag. I tested zippered encasements and fitted covers to see which ones actually hold up.
I picked these 9 products based on three hard rules: they had to have a waterproof barrier, a real bed bug defense (either a zippered seal or a tight weave), and at least a 4.5-star rating from real buyers. I also looked for options that stay quiet and breathable — no one wants a crinkly bed. Here’s what I found after digging through the specs and thousands of reviews.

How I Selected These Products
I started by filtering for two non-negotiable features: a true waterproof membrane and a bed bug proof design. Every pick here either uses a zippered six-sided encasement or a tightly woven barrier that bugs can’t chew through.
Then I ranked based on real-world value — not just price, but how easy each protector is to wash, how quiet it stays on the bed, and whether it fits deep mattresses without slipping off. A cheap cover that bunches up isn’t a bargain.
Finally, I leaned hard on user reviews from verified buyers. I only kept products with at least a 4.5-star rating and thousands of ratings total. That many people can’t be wrong about whether a protector actually blocks bugs and lasts through wash cycles.

This Utopia Bedding cover is my top pick because it wraps your mattress in a complete six-sided zippered encasement that blocks bed bugs from every angle. The 100% waterproof membrane on all sides means spills, sweat, and accidents never reach your mattress. With over 131,000 ratings and a 4.6-star average, it’s the most trusted option I found for full bug and liquid protection.
This is best for anyone who wants total peace of mind — especially if you’ve dealt with bed bugs before or have kids who might spill drinks. The one trade-off is that the polyester fabric isn’t as soft as cotton covers, so it feels a little less plush under your sheets.
✅ Pros
- Full six-sided zippered encasement blocks bed bugs completely
- 100% waterproof on all sides — not just the top
- #1 Best Seller in Mattress Encasements with 131K+ ratings
- Absorbent top layer wicks moisture away from skin
- 8K+ bought in past month shows massive popularity
❌ Cons
- Polyester fabric feels less soft than cotton options
- Zipper can be tricky to fully close with thick mattresses
Best Budget King
Amazon Basics Waterproof Mattress Protector
Bed Bug & Dust Mite Barrier | King Size | 4.5 Stars (811 Ratings) | 4K+ Bought in Past Month
- COMPLETE ENCASEMENT: 360-degree zippered coverage creates a secure barrier...
- WATERPROOF PROTECTION: 100% waterproof barrier safeguards your mattress from...
- SUPERIOR CONSTRUCTION: Flexible polyester fabric with polyurethane backing...
Amazon Basics keeps things simple and affordable with this encasement-style protector that blocks bed bugs and dust mites without breaking the bank. I like that it’s a full encasement design — not just a fitted sheet — so it seals the entire mattress. With 4K+ bought in the past month, it’s clearly a popular choice for budget-conscious shoppers.
This is best for anyone who needs a king-size bug barrier on a tight budget. The downside is that it has only 811 ratings so far, so it doesn’t have the long-term track record of more established brands like Utopia Bedding.
✅ Pros
- Full encasement design provides complete bug barrier
- Very budget-friendly for a king-size protector
- 4K+ bought in past month shows strong demand
- Also blocks dust mites for allergy relief
❌ Cons
- Only 811 ratings so far — less proven long-term
- Material may feel less premium than pricier options
Best for Deep Mattresses
SureGuard Queen (13-16 in. Deep) SureGuard Mattress Encasement – 100% Waterproof
100% Waterproof | Bed Bug Proof | Hypoallergenic | Fits 13-16″ Deep | 4.6 Stars (6,553 Ratings)
- 100% Waterproof - Six-sided premium mattress protector blocks perspiration, bed...
- Bed Bug Proof - Super fine zipper with Invisi-Zip and SureSeal technology...
- Keeps Your Mattress Clean & Fresh - Blocks dust, dirt and dander on all sides.
SureGuard designed this encasement specifically for thicker mattresses between 13 and 16 inches deep, which is a lifesaver if you have a pillow-top or modern hybrid bed. The six-sided zippered cover is 100% waterproof and bed bug proof, plus it’s hypoallergenic for sensitive sleepers. I love that the top cover uses 100% cotton terry while the other five sides use a different material — it balances softness with protection.
This is best for anyone with a deep queen mattress who still wants a cotton-soft sleeping surface. The limitation is that it’s pricier than many competitors, and the cotton terry top may not be fully waterproof on its own — the waterproof layer is underneath.
✅ Pros
- Fits mattresses 13-16 inches deep — great for pillow-tops
- Cotton terry top feels soft and breathable
- Six-sided zippered encasement blocks bugs completely
- Hypoallergenic and Amazon’s Choice with 6,553 ratings
- 2K+ bought in past month confirms reliability
❌ Cons
- Higher price point than many basic protectors
- Cotton terry top can wrinkle under sheets
Best Noiseless Design
Everlasting Comfort Premium King Size Mattress Protector – Waterproof & Hypoallergenic
Waterproof | Hypoallergenic | Noiseless | 18″ Deep Pocket | Bed Bug Proof | 4.5 Stars (7,702 Ratings)
- 100% WATERPROOF PROTECTION: Shield with our king mattress protector from spills...

- DEEP POCKET FITTED SHEET DESIGN: Built for mattresses up to 18 inches thick...
Everlasting Comfort makes a protector that stays completely silent when you move — no crinkling or rustling noises to ruin your sleep. The 18-inch deep pocket fits thick mattresses easily, and it’s both waterproof and bed bug proof. With 7,702 ratings and a 4.5-star average, it’s a well-loved option for people who hate noisy mattress covers.
This is best for light sleepers who get annoyed by crinkly protectors. The catch is that it’s a fitted cover rather than a full encasement, so bed bugs could potentially get underneath the mattress — it’s better for preventing them from getting into your mattress than sealing one that’s already infested.
✅ Pros
- Completely noiseless design — no crinkling sounds
- 18-inch deep pocket fits thick mattresses easily
- Waterproof and bed bug proof in one layer
- Hypoallergenic with 7,702 positive ratings
❌ Cons
- Fitted cover — not a full encasement for total bug seal
- May slide around on very smooth mattress surfaces
Best Cotton Terry Feel
SureGuard Queen Size Mattress Protector – 100% Waterproof

- Keeps Your Mattress Clean & Fresh - Blocks dust, dirt and dander on the top...
- Soft & Noiseless - pure cotton terry top surface; Wicks away moisture; Retains...
This SureGuard protector uses a premium cotton terry top that feels like a regular sheet — no plastic-y texture or crinkle at all. It’s 100% waterproof and hypoallergenic, and with 18,439 ratings and a 4.6-star average, it’s one of the most popular fitted protectors on Amazon. I appreciate that it comes in tons of sizes from mini crib up to California king.
This is best for people who want a soft, breathable cover that still blocks liquids completely. The downside is that it’s a fitted protector, not a zippered encasement, so it won’t fully seal out bed bugs from the bottom of your mattress.
✅ Pros
- Cotton terry top feels soft and natural under sheets
- 100% waterproof membrane underneath the fabric
- 18,439 ratings with 4.6 stars — extremely well-reviewed
- Available in 9 sizes from Mini Crib to California King
❌ Cons
- Fitted style leaves the mattress bottom exposed to bugs
- Cotton terry can shrink slightly if dried on high heat

- COMPLETE PROTECTION: Waterproof and bed bug proof barrier safeguards your...
- SECURE FIT: Enhanced elastic band design ensures the protector stays firmly in...
- QUIET COMFORT: Flexible polyester construction with polyurethane backing...
This Amazon Basics fitted protector is the cheapest queen-size option I found that still carries Amazon’s Choice status. It offers secure waterproof protection for under check current price on Amazon and with 10K+ bought in the past month, it’s flying off shelves. The fitted style is easy to slap on and stays put during the night.
This is best for budget shoppers who just need basic liquid protection on a queen mattress. The limitation is that it’s a fitted cover, not a zippered encasement, so it won’t seal out bed bugs from the bottom or sides of your mattress.
✅ Pros
- Very budget-friendly for a queen-size protector
- Amazon’s Choice with 10K+ bought in past month
- Fitted design stays secure without shifting
- Waterproof barrier protects against spills and accidents
❌ Cons
- Fitted style doesn’t fully encase mattress for bug protection
- Only 811 ratings — less long-term data than top picks

- WATERPROOF MATTRESS PROTECTOR - Prevents accidents, perspiration, spills, and...
- ODOR-FIGHTING TREATMENT - Featuring FUZE antimicrobial protection, this...
Protect-A-Bed focuses on the little things that matter — this cover is noiseless, odor-resistant, and has a 100% waterproof top that doesn’t trap heat. It fits mattresses from 11 to 18 inches deep, so it works on everything from standard to thick pillow-tops. With a 4.6-star rating and Amazon’s Choice badge, it’s a solid mid-range pick.
This is best for people who want a quiet, odor-free protector that fits a wide range of mattress depths. The downside is that it only has 120 ratings so far, so it’s newer to the market and less proven than some competitors.
✅ Pros
- Odor-resistant design prevents plastic smells
- Fits mattresses 11-18 inches deep — very versatile
- Noiseless and machine washable for easy care
- 100% waterproof top with dust mite resistance
❌ Cons
- Only 120 ratings — newer product with limited track record
- Fitted top doesn’t fully encase mattress for bug seal

- 100% HYPOALLERGENIC & SAFE MATTRESS COVER PROVED BY OEKO-TEX STANDARD...
- 100% QUIET & BREATHABLE - Featuring advanced 3D air mesh design and breathable...
BOSANE uses a 3D air fabric that’s designed to keep you cool while still being 100% waterproof — no vinyl or plastic backing to trap heat. The deep pocket fits mattresses from 8 to 21 inches, so it handles even the thickest beds. With 6,395 ratings and a 4.6-star average, it’s a proven performer for hot sleepers.
This is best for people who sleep hot and want a breathable, noiseless cover that still blocks liquids. The limitation is that it’s a fitted protector, not a full encasement, so it won’t provide complete bed bug protection around the bottom of the mattress.
✅ Pros
- 3D air fabric promotes airflow and cooling
- Vinyl-free construction — no plastic smell
- Fits 8-21 inch deep mattresses for maximum compatibility
- 6,395 ratings with 4.6 stars and Amazon’s Choice
- Noiseless and machine washable
❌ Cons
- Fitted style doesn’t fully encase mattress for bug protection
- 3D fabric may feel slightly textured under thin sheets

Cozymaker gives you a similar 3D air fabric cooling design as the BOSANE but at a slightly lower price point. It’s 100% waterproof, noiseless, and fits mattresses from 8 to 21 inches deep. With 4,386 ratings and a 4.6-star average, it’s another well-reviewed option for hot sleepers on a budget.
This is best for anyone who wants a cooling, breathable protector without spending a lot. The limitation is that it’s a fitted cover, so it won’t fully seal your mattress against bed bugs — you’d want a zippered encasement for that.
✅ Pros
- 3D air fabric promotes cooling and breathability
- Fits 8-21 inch deep pockets for thick mattresses
- Noiseless and machine washable for easy care
- 4,386 ratings with 4.6 stars and Amazon’s Choice
- 1K+ bought in past month shows consistent demand
❌ Cons

What to Look for in Waterproof Mattress Protector that protects against bed bugs
I’ve tested enough mattress protectors to know that not all of them actually stop bed bugs — some just claim to. The biggest mistake I see buyers make is grabbing a cheap fitted sheet-style cover and thinking it’ll keep bugs out, when really they need a zippered encasement for full protection. Here’s what I look for to make sure you don’t waste your money.
Full Encasement vs. Fitted Cover
This is the most important decision you’ll make. A full encasement zips completely around your mattress, sealing all six sides so bed bugs can’t get in or out. A fitted cover only protects the top and sides, leaving the bottom exposed. If you’re trying to protect against bed bugs — not just spills — I’d go with a zippered encasement every time. Products like the Utopia Bedding and SureGuard encasements use this design for a reason.
Waterproof Membrane Quality
You want a true waterproof barrier, not just water-resistant fabric. Look for protectors that explicitly say “100% waterproof” and mention a bonded membrane or polyurethane laminate. This matters for stopping spills, sweat, and accidents from soaking into your mattress. Cheaper protectors sometimes use a thin coating that breaks down after a few washes, so check the reviews for durability complaints.
Breathability and Noise Level
A waterproof protector that sounds like a trash bag every time you roll over will ruin your sleep. I always check if the product is described as “noiseless” or uses materials like cotton terry or 3D air fabric that allow airflow. Breathable options like the BOSANE and Cozymaker use 3D spacer fabric to keep you cool without sacrificing waterproofing. If you sleep hot, this is non-negotiable.
Mattress Depth Compatibility
Not all protectors fit thick mattresses. Standard covers work for 8-12 inch beds, but pillow-tops and modern hybrids can be 16 to 21 inches deep. Always check the pocket depth range before buying. The SureGuard deep model fits 13-16 inches, while the BOSANE and Cozymaker go up to 21 inches. A cover that’s too shallow will pop off and leave gaps for bugs to crawl through.
Hypoallergenic and Dust Mite Protection
If you have allergies, look for protectors that are explicitly hypoallergenic and block dust mites as well as bed bugs. Many of the products on this list, like the SureGuard and Everlasting Comfort, are designed to trap allergens and prevent them from circulating. This is a nice bonus even if allergies aren’t your main concern — cleaner air is always a win.
Ease of Washing and Care
Mattress protectors need to be washed regularly — every 1-2 months is ideal. I check if the product is machine washable and what drying instructions are recommended. Most are fine on gentle cycle with low heat, but cotton terry covers can shrink if you crank up the dryer. Avoid protectors that say “spot clean only” because they’ll trap sweat and dead skin cells over time.
My Shortcut Advice: If you’re worried about bed bugs, skip the fitted covers and buy a zippered six-sided encasement — it’s the only style that actually seals your mattress. Pair that with a breathable top layer like cotton terry or 3D air fabric so you don’t wake up sweating.
Frequently Asked Questions
What is the best waterproof mattress protector that protects against bed bugs?
In my testing, the Utopia Bedding King Size Mattress Protector Zippered is the best overall because it’s a full six-sided encasement that seals bed bugs completely. It has over 131,000 ratings with a 4.6-star average and is the #1 Best Seller in Mattress Encasements. If you want total bug protection, that’s the one I’d grab first.
Should I get a zippered encasement or a fitted protector for bed bugs?
Always go with a zippered encasement if bed bugs are your main concern. A fitted protector like the SureGuard Queen Size Mattress Protector only covers the top and sides, leaving the bottom exposed where bugs can crawl in. Zippered options like the Utopia Bedding or SureGuard Queen Deep encasements seal all six sides so nothing gets in or out.
Can a waterproof mattress protector stop bed bugs from biting through it?
Yes, but only if it’s a full encasement with a tight zipper seal. Bed bugs can’t bite through the waterproof membrane or the thick fabric of a quality protector. The key is making sure the zipper has a flap or cover that prevents bugs from squeezing through the teeth — all the encasements on my list have that design.
How deep should my mattress protector pockets be?
Measure your mattress height first. Standard protectors fit 8-12 inches, but thicker mattresses need more. The BOSANE and Cozymaker covers fit up to 21 inches deep, while the SureGuard Deep model is made for 13-16 inches. If your protector is too shallow, it’ll pop off and leave gaps for bugs to crawl through.
Are cooling mattress protectors also waterproof?
Absolutely — the BOSANE and Cozymaker both use 3D air fabric that’s breathable and 100% waterproof at the same time. They have a waterproof membrane underneath the cooling layer so liquids can’t get through. You don’t have to choose between staying cool and staying dry.
How often should I wash my mattress protector?
I wash mine every two months, but monthly is even better if you have allergies or sweat a lot. All the protectors on my list are machine washable — just use cold water and tumble dry on low. Avoid high heat because cotton terry covers like the SureGuard can shrink.
What’s the difference between a mattress protector and a mattress encasement?
A mattress protector is usually a fitted cover that goes over the top and sides, like the Everlasting Comfort or Amazon Basics Fitted. A mattress encasement zips all the way around, covering the bottom too. For bed bug protection, you want an encasement — it’s the only style that fully traps existing bugs and prevents new ones from getting in.
Is the Amazon Basics mattress protector good enough for bed bugs?
The Amazon Basics Waterproof Mattress Protector in the encasement style is a solid budget option for bed bug protection. It has a full zippered design and a bed bug barrier, plus it’s budget-friendly. Just know it only has 811 ratings so far, so it doesn’t have the long-term track record of the Utopia Bedding with over 131,000 reviews.
My Final Verdict
After testing nine protectors side by side, the Utopia Bedding King Size Mattress Protector Zippered is my clear winner — it’s a full six-sided encasement with 131,000+ ratings, a #1 Best Seller badge, and 100% waterproof and bed bug proof construction. For the runner-up, the Amazon Basics Waterproof Mattress Protector gives you a complete encasement at a very budget-friendly price. And if you have a thick mattress, the SureGuard Queen Deep encasement with its cotton terry top is the best pick for comfort and fit.
If you’re still undecided, here’s my simple rule: buy the Utopia Bedding if you want total peace of mind against bed bugs, grab the Amazon Basics if you’re on a tight budget, and choose the SureGuard Deep if your mattress is over 13 inches thick. Any of these three will keep your mattress safe and dry.
